Design a Banner for Devil Racing car and audio

Konkurrence Instruktioner

Need a 4:1 ratio banner / bumper sticker designed, to incorporate the name Devil Racing (can be all caps) and a picture of both a horned skull and separate subwoofer (either side), or a combination subwoofer horned skull (to one side).

I would like to be able to have it cut from vinyl, so the design can't have fine detail in it.

Must be recognisable (like a brand)

If you can incorporate the obligatory 666 in there, that would be a bonus.
